Hi Roland:

Hi John, Ethan, and Rich (who hopefully isn't reading email on vacation this week),
Tom pointed this out to me. We were trying to figure out if this meant that "DAP was dead" and we need to shop for a new protocol or if this just meant that the opendap.org guys were done with the java implementation.
DAP4 is very much alive, but the java implementation is not much of a priority for opendap.org, although they do bug fixes on it. They are mostly working on their C++ sever code (Hyrax). Unidata has been the main support for the opendap Java library for the past several years. We are currently talking about it's future - probably we will rewrite it to be better integrated into our CDM software stack, and essentially take ownership of it. We already have rewritten the opendap C library for netcdf clients, so this would be continuing that path.

(Please someone correct me if I'm wrong!) The only HTTP method call in DConnect2 is GET (e.g. org.apache.commons.httpclient.methods.GetMethod). However it appears to be making a HEAD calls too even though HeadMethod is not called directly. Also, is HTTP HEAD required for the DAP 2 spec?
